The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for Lakey Pipe. This is a reef break that's exposed to the SW, and the guidance tells us it's a spot that likes a solid SW swell, which is exactly what we're seeing. Over the next two and a half weeks, we've got a consistent pulse of groundswell, but don't expect perfect conditions every day. The first real standout to circle on your calendar is Saturday morning, the 14th of September, with Sunday the 15th of September offering another cracker.
The Pattern
The action kicks off on Wednesday morning, 2nd of September, with a clean 7 ft SW groundswell (moderate energy 2561). It's a little marginal with a cross-off wind, but it's a start. We'll have similar, slightly smaller surf over the next couple of days. The real quality starts to settle in on Friday morning, the 4th, with a cleaner 5 ft SW swell, and we start seeing some better conditions.
The water temperature sits around 81°F with a small anomaly of 0.9°F, so it's about what you'd expect for this time of year—warm and tropical.
The Standout Sessions
Hold on for Saturday morning, the 14th of September. This is the one. We've got a very clean 10 ft SW groundswell pumping in from an 18-second period. That's a proper, long-period groundswell, and the combined energy is a full-on 5419—that's strong. The wind is a light cross-offshore at 9 mph. This is serious, expert-level stuff. That 10 ft is well over the 8 ft mark, so it's for experienced surfers only. The kooks should sit this one out and watch from the beach. The following morning, Sunday the 15th, is a close second. It's another clean morning with an 8 ft SW swell at 15 seconds (energy at 3301), with light cross-offshore wind. Fantastic, high-quality surf.
The Rest of the Run
From the 4th through the 12th of September, there's a good solid run of chest to head-high SW swell, mostly in the 5 ft to 7 ft range. Most afternoons get a bit of a cross-shore breeze, but the mornings are consistently clean thanks to the cross-offshore wind from the SSE or SE. The crowd factor here is "often," so expect company, but the consistency on offer means there will be plenty of waves to go around. The 2nd week, starting around the 10th, keeps offering clean, solid morning surf, with the swell hanging in around 6 ft to 8 ft. It's a reliable pattern.
A quick note on the 12th of September: the Saturday afternoon session sees the swell dip to 5 ft but the period jumps to 21 seconds. The combined energy is still 3312, so there's plenty of power there, but a period that long can make a reef break like this a bit fat and straight. Still worth a look, early.
Later in the forecast, the 16th of September brings another solid morning with an 8 ft SW swell at 17 seconds, and the 17th of September (Thursday) serves up a clean 8 ft – 8 ft SW groundswell with very light wind. The pattern holds strong.
Make no mistake, Lakey Pipe is on. The first wave is on Wednesday, 2nd September, and the best window is locked in for the morning sessions, especially the 14th, 15th, and 17th.
Rusty, signing off.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
